由Fraunhofer太陽能系統協會和真理調查局聯合發表聲明顯示，AEG能源解決方案protect PV250太陽能逆變器的能源轉換率效果驚人。
根據歐洲標準EN50530能源轉換效率測試顯示，該逆變器的轉換效率高達98.7%。
AEG能源方案，由3W能源公司全資擁有。該集團是一個全球尖端電力能源供應商。該AEG系統經過八個不同的電力水平測試，9個直流電壓水平測試和兩種組件科技測試（晶硅組件和薄膜電池組件，兩者都是用于光伏電廠）以及根據同樣的歐洲EN50530標準下由ISE指導下的MPPT測試。
21.07.2010: A report jointly issued by the Fraunhofer Institute for Solar Energy Systems (ISE) and Bureau Veritas shows that AEG Power Solutions’ Protect PV.250 solar inverter offers remarkable efficiency. Energy conversion efficiency testing conducted according to European Standard EN 50530 yielded a very high efficiency grade of 98.7%.
AEG Power Solutions, wholly-owned by 3W Power Holdings S.A. (Euronext Amsterdam 3WP, ISIN GG00B39QCR01, WKN A0Q5SX), is a global provider of premium power electronics. Energy conversion efficiency testing was conducted at eight different power levels, nine DC voltage levels and for two module technologies (thin film and crystalline technology, both used in solar farms). MPPT testing, performed by ISE according to the same European EN 50530 standard, yielded a Maximum Power Point (MPP) efficiency grade of 99.99%. ISE also reported that the
PV.250 inverter, launched in Sept. 2009, successfully complied with EN 50530 dynamic  requirements. …
